Are details of the Tau2 optical interface available for customers that want to use a third-party lens with the camera?

A mechanical Interface Description Document (IDD) is available as an Appendix to the User`s Guide. The current Tau2 User`s Guide can be downloaded here. The specific drawing to reference is Figure D-1 on page D-1.

The IDD should provide sufficient optical interface detail to allow customers to design or specify a third party lens.
